摘要
以国内首例的较深水海管带压开孔项目为背景,全面地介绍海管维修工程中带压开孔及临时封堵技术应用的方案设计、施工流程及注意事项。通过对水下带压开孔及临时封堵的海管维修作业进行分析,确立了较深水海管带压开孔的一般工艺流程。
Based on the f irst deepwater domestic hot-tapping project, the program design, construction process and attention issues about hot-tapping and temporary plug are compre-hensively analyzed. Through the research of hot- tapp in g and temporary plug for deepwater pipeline, the general construction process is founded.
